Ardeadactylus
''Ardeadactylus'' (from ''Ardea'' – meaning "heron", and also a name of a genus of herons – and ''dactylus'', meaning "finger") is an extinct genus of pterodactylid archaeopterodactyloid pterosaur known from the Late Jurassic Solnhofen limestone of Bavaria, southern Germany. It contains a single species, ''Ardeadactylus longicollum'', which was originally thought to be a species of ''Pterodactylus''.
Only two specimens of ''Ardeadactylus'' are known to exist currently: SMNS 56603 (earlier SMNS 5802) found in 1874, a specimen from Nusplingen initially thought to belong to the species ''Pterodactylus suevicus'' Quenstedt (currently ''Cycnorhamphus'')〔Fraas, O., 1878, "Über ''Pterodactylus suevicus'', Qu., von Nusplingen", ''Palaeontographica'', 25: 163-174〕 and the neotype of the species, and JME-SOS 2428, a specimen held at Jura Museum in Eichstätt. Other known specimens, including the holotype designated by Christian Erich Hermann von Meyer when he named the type species ''Pterodactylus longicollum'' in 1854,〔Meyer, C.E.H. von, 1854, "Mittheilungen an Professor Bronn: Anthracotherium Dalmatinum vom ''Monte Promina'' u.a. A.; Chelydra Decheni aus Braunkohle des ''Siebengebirges''; Wirbelthier-Reste aus dem Basalttuff-Konglomerat zu ''Glimbach'' an der ''Rabenau''; angebliches Vorkommen von Agnotherium antiquum und Hyaena spelaea; fossile Reste im lithographischen Schiefer von ''Nusplingen'' bei ''Spaichingen''; Eryon Schuberti; Litogaster; Pemphix; Pterodactylus longicollum n. sp. in ''Solenhofener'' Schiefer; Acrosaurus Frischmanni von da; Reptilien und Cancer-Arten im ''Kressenberger'' Nummuliten-Gestein", ''Neues Jahrbuch für Mineralogie, Geognosie, Geologie und Petrefaktenkunde'' 1854: 47-58〕 were lost during World War II.〔 The original holotype, consisting of the skull, neck and anterior torso, had been found near Eichstätt in 1853 and was that year acquired for the ''Herzoglich Leuchtenbergische Naturalien-Kabinett'' by Professor Ludwig Frischmann.〔 Its destruction motivated Peter Wellnhofer to assign a neotype in 1970.〔Wellnhofer, P., 1970, "Die Pterodactyloidea (Pterosauria) der Oberjura-Plattenkalke Süddeutschlands", ''Bayerische Akademie der Wissenschaften, Mathematisch-Wissenschaftlichen Klasse, Abhandlungen'' 141: 1–133〕
''Ardeadactylus'' is suspected to be a heron–like, long–necked long–legged piscivore.〔 It was similar to ''Pterodactylus antiquus'' in its general body form, but seems to have been larger. Bennett (2013) estimated the wingspan of the neotype specimen to be ; the referred specimen from the Jura Museum is more or less 10% larger.〔 ''A. longicollum'' had fewer, fifteen per jaw, and relatively larger teeth than ''P. antiquus'', possibly indicating that it preyed on larger fishes than ''Pterodactylus''.〔
